Froggicus Mentis

First identified by Patient 19 during an unsupervised excavation behind the hydrotherapy wing, Froggicus Mentis is a low-crawling cortical amphibian believed to have spontaneously generated from a failed cognitive therapy experiment. Though outwardly silent, it emits a low-frequency thought-hum that causes dizziness and brief nostalgia in nearby observers.It feeds exclusively on spilled ink, crossword puzzles, and the memories of things you forgot to write down.
